.conditions in road beds.

One of the objects of the invention is to devisea simple and efiicient machine adapted to shave the surface of the road, together with suitable provision for adjustment for varying the character of the shaving operation for varying conditions of the road bed.

It is also an'object to provide an apparatus of this type which will be arranged to deflect the shaved material to. one side of the shaved surface, and also equipped with adjustable means for packing said shaved material in its new position.

It is. also sought to provide a simple, and

durable arrangement and construction for accomplishing theseresults, with a view to employing as few parts as possible and embodying the same in an apparatus which will be economical and inexpensive to manufacture. f 1

With these general objects in view, the

invention will'now be described with reference to the accompanying drawings illustrating one form of construction for embodying the improvements, after which those features: and combinationsdeemed to benov el'will be set forth and'defined in the appendedclaims.

In the drawings Figure 1 is a perspective view of an apparatus constructed in accordance with the 45,

present invention; 1

Fig. 2 is a plan view of the same; Fig. 3 is a side view;

Figs. 4 and 5 are enlarged sectional views takenon'the lines -IV.IV and V-V, respectively, of Fig.2; I

Fig. 6 is a side view of a portion of the frontend of the machine, looking in the opposite direction=from Fig. 3 and on a s i ht y larger S a 1 Fig. 7 is a'detail section taken on the line VIIVII of Fig. 2 but on a larger scale, and

Fig. 8 is a similar enlarged detail section taken on the line VIII-VIII of Fig. 3.

Referring to the drawings in detail, the supporting framework of the apparatus comprises a front angle bar 2 connected with a yoke casting 4 carried by the flanged wheel 6, to which casting member is connected in a suitable manner a draft tongue 8 and also the front end of a longitudinally extending bar 10. The rear end of the bar 10 is loosely connected to the end of a bolt 12 which is secured to the upright frame piece 14. To this upright member 14 is secured the rear ends of a pair of angle bars 16 and 18, one'above the other and inclined toward each other in the direction of the wheel 6 and having their front ends securedto the frame of a rack segment 20, the angle bar 18 being also secured to one end of a transversely extending angle bar 22 the other end of which' makes loose pivotal'connection by means of a bolt 24 gvith the extreme outer end of the front ar 2. The corner of the interior frame work 1618-22 which carries the rack segment 20 is supported on the bar 10 by means of a roller 26 carried by the lever 28 pivoted at 30 (see Fig. 6) to said interior framework "and provided with the spring-actuated pawl 32 for latching engagement with said rack segment. It will thus be apparent that said interior framework, may be rocked, by means of said lever, about the bolt connections 12 and 24 and latched in the desired adjusted position.

The-framework which has just been described is adapted to support the road shaving means in diagonally extending relation to theroad bed. The road shaving tool consists of a two-edged knife or blade 34 having a smooth under surface and secured by bolts36 to one of the flanges of a steel channel beam 38in a manner adapting said blade to be carried in almost parallel relation to the road surface for efl'ectinga shaving cut thereon, said blade traveling for the most part below the level of the road surface. The beam 38 is secured about midway between its ends to the lower end of the upright frame piece 14, and at its front end is provided with a casting 40 having an upwardly projecting arm l2 which is secured to the bolt 24 Secured by bolts 44 to this casting 40 is also provided a nose knife 4:6 which deviates forwardly from the line of the knife or blade 34 and is provided with a cutting edge which extends upward from the plane of said blade 34. The casting 40 is also formed with a bearing l8 for slidingly and pivotally accommodating the angular axle 50 of a caster wheel 52. Also secured to the casting 4-0 is a bracket 51 pivotally connected by a link 56 with a lever 58 which is mounted on a rack segment 60 fixedly secured to the upper end of the axle 50, said lever carrying the spring-actuated pawl 62 for latching engagement with the rack of said segment 60.

The blade is only about two-thirds the length of the beam 38, the rear portion of the latter permitting the shaved earth material to be deposited in the path of a packing roller 6% which is carried on an axle 66 having the opposite ends thereof supported in boxings 68, one of which boxings is secured by rods 70, 72, and turnbuckle 73 to a plate 74: bolted to said beam 38 adjacent the midportion of the latter; the other boxing 68 is carried by a plate 76 loosely held by a bolt 78 carried by a bracket casting 80 which in turn is secured to the rear end of the beam 38. The roller 64, the opposite ends of which are provided with the flanges 82 for preventing axial movement -of the roller, may be adjusted to bring the axis thereof into more or less tilted position with relation to the road bed by means of a crank bolt Sl threaded through said bracket casting 80 into engagement with the plate 76 whereby the latter maybe swnng into different positions with relation to its pivotal support 78, a jam nut 86 being provided for securing said bolt 84 in adjusted position. Obviously also the roller may be adjusted to bring one end of its axle 66 in advance of the other by appropriate adjustment of the turn-buckle 73.

A yoke-shaped seat bar 88 is secured to the beam 88 and bar 16 respectively, and carries a seat 90 in convenient position for enabling the driver to operate the levers 28 and 58.

It will thus be apparent that an efficient and comparatively simple arrangement and construction have been devised for carrying out the desired objects of the invention. The cutting or shaving blade 34, carried in the diagonal relation shown, operates to shave the top surface of the road bed, leaving a smooth and hard surface of the desired contour, and deflecting the shaved material into the path of the roller, which smoothes and packs said material along the middle portion of the road bed. It is found that the operation of this apparatus gives results superior to those ordinarily obtained by any of the loose earth methods, as it enables the contour outline of the road bed surface to be kept more uniform and more nearly according to the desired outline, and moreover the shaved surface, when treated with oil, absorbs the oil better and gives as nearly a true paved surface as can be obtained with earth and oil. The shaved surface is left firm, hard and smooth and does not require to be packed, but is ready at once for heavy traffic; and, if treated with oil, the surface will drain perfectly, in contrast with loose or imperfectly packed earth after treatment with oil. The lever '28 enables the framework carrying the shaving blade to be tilted about an axis extending substantially longitudinally of the blade so as to present the latter at the proper cutting angle to the road bed; and the blade is also tilted endwise or about a transverse axis by means of the lever 58 operating to raise or lower the front end of the blade, as will be readily understood, this latter adjustment being of course for the purpose of regulating the lateral slope of the road bed. The nose knife 46 serves as an entering element, cutting loose the shaved material at the forward end of the shaving blade and acting to start the defleeting movement of said material along the blade in the direction of its other end. Said blade is detachably mounted on the beam 38,

and having the duplex cutting edge arrangement it may obviously be readily removed when one edge has become dull, and reversed in position and applied with its other cutting edge in position for shaving.

While the foregoing illustrates what is now deemed to constitute the preferred form of embodiment of the improvements, the right isreserved to all such formal changes or niodlfications as may fairly fall Within the scope of the appended claims.

I claim:
